To {LIZ Ir itant fl WL/Z-l/ concern:

Be it known that I, GoTTLIEn GLoontun, a German subject, and a resident of Stutt art, Vihiricmherg, Germany, (post-office adr ress 51 Guttenbergstrasse) have invented certain new and useful Improvements in Steam and "Water Conductors for High and Low Pres A further object of the invent-ion is to pro duce a device which will automatically empty itself of water to prevent freezing.

With those objects in view my'invention consists in the construction and combinations oi parts, as hereinafterdescribed and claimed.

n tln accompanying drawings, Figure l is a longitudiind section of the device; and Fig. 2 is a cross-section of the same, taken on the line A B of 1.

The device consists of a casing 1, circular in general outlinc,c:\'ccpt that on one side it is expanded, as shown at c, for the passage of hot water Without This casing 1 is provided at one end \v1tha discharge-opening d and at the other end with a removable head 2, secured there on in any desired manner. Through this head 2 bored a passage (1, provided, as snown, with screw-threads, whereby it may bratiachcd to the other parts of the system.

10 represents a casing slipped into the pas sngc a. and provided at its top with an iu-- cliucd sieve )1 for the purpose of catching any impurities carried along by the hot Water.

At the boitomol the device is h-rcatcd a plalc.

i, which may be adjusted up and down by means of n screw 71. This plate is perforated, as shown at e, to allow any vector that may be above the same to drain out. ()n the plate 71 is loosely mounted a brass tube 5, open at both ends.

6 represents a tube of iron or steel or some other material, which is loosel mounted on thctubc 5 by means of the ange 7; The tube- 6 is flanged at the bottom, as shown at affecting the expansion- 8, and on this flange rests anothcrbrass tube 9. This structure is repeated until a series oi. concentric tubes alternately of brass and iron or steel is formed, which acts to close the valve m, which has a tapered end b when steam passes through the apparatus by reason of the fact that brass expands under the infiu-- ence of heat more than iron.-

The valve m is mounted on the inner tube of the expansion series and is adapted to lit against a seat 57. inserted in, the head 2. 1 represents a plate fastened to the inner tube of this series, which plate serves the double purpose of deflecting the water into the passage c and of forming a seat for the spring lc, one end of which rests on said plate and the other end of which bears against the he rl 2, the tendency of said sprin being always to kce the valve open. The lead 2 is provided with a passage p, nearly right-angled in shape, surrounding one part of which is the valvescat 11, with which the pointed end 12 of a valve 0 engages. operated when it is desired to clean out the device by blowing steam thcrethrough, which of course carries with it the impurities that may have been deposited by the water on the inclined sieve n.

q represents a removable screw passing through the side of the casing 1, which is removed during the clcansing o oration. Attsr the valve 0 has been opens and steam allowed to llow through the apparatus and after the steam begins to escape freely through the opening left by the removal of the control-screw q the operation is stopped.

Having thus described my invention, what I claim as new, and desire to secure in y Letters Patent of the United States, is-

1. In a conductor, the combination of a casing open at both ends, a valvc in. said casing and a thermostatic device forautomatically closing said valve when the temperature rises too high, said device consisting of a series of plain cylindrical tubes and a series of cylindrical tubes arranged alternately and concentrically in relation to said first-named series, said second-named series being provided with horizontal flanges at the top and at the bottom, said flanges projecting m opposite directions, whereby loot'h series of tubes are loosely supported in contact with each other, a support for the outer cylindrical tube of the first-named series, and means for ad justing said support, substantially as described.

This passage and valve are" 2. In a steam water-conductor, the combination of a casing normally open at both ends, a valve adapted to automatically close the passage in said casing when the temperaturo rises too high, a spring normally ho ding through said casing, said device consistin r of said valve open, and a thermostatic device for automatically closing said valve when steam begins to flow throu h said casing.

consisting of a series of plain cylindrical, to tubes, a second series of cylindrical tubes al- I ternatmg with said first-named series, both series of tubes being arranged concentrically, said second-named series being provided with flanges at the top and bottom extend- I in in o )osite directions said valve bein 17 1 Z) connecte to the inner tube of said series, a perforated plate for supporting the outer tube of said series of tubes, and a screw for adjusting said plate, substantially as described.

3. In a steam water-conductor, the conibination of a casing provided with a passage therethrough, a sieve in said passage, a valve adapted to close said passage a spring for normally holding said valve open, and a thermostatic device for automatically closing said valve when steam flows through the casing, consisting of a series of plain cylindrical tubes, a second alterni'itely-arranged series of cylindrical tubes, said two series being composcd of metals of different cxiansibilities under the influence of heat, sai second series of tubes being provided with horizontal tlan gcs extending in opposite directions, whereby the'whole series of tubes is supported, the one upon the next, a perforated plate on which the outer tube rests, and a screw for adjusting said plate, substantially as described. 4. In a steam Water-conductor, the com- 4o,- $iination of a casing provided with a passage 'therethrough, said (passage being enlarged on one side to provi e for al'ree flow of auid therethrough, a valve adapted to close said automatically close said valve against the tension of said spring when steam flows a series of plain tubes composed of meta of one expansibility, alternating with a second series of cylindrical tubes composed of metal of a difl'orent expansibility, said second series being provided with oppositely-extending flanges at the top and at the bottom, whereby all the tubes are supported the one on the other, av perforated plate on which the outer tube rests, a screw for adjusting said plate, and a sieve located in said passage, substantially as described.

the casing, consisting of a series of cylindrical brass tubes arranged concentrically with relation to each other, and a second series of cylindrical iron tubes provided with oppositely-projecting flanges at the top and t 1e bottom, said irontubes being arranged alternately with relation to said brass tubes; a perforated plate for supporting the outer brass tube, a screw for adjusting said plate, a sieve in said passage, and a. control-screw in the side of the casing, substantially as de scribed.
